Rick Santorum doubled down today on his comments about President Obama, race, and abortion, again comparing the constitutional rights of the "unborn" to the constitutional rights of black people: "I am disappointed that President Obama, who rightfully fights for civil rights, refuses to recognize the civil rights of the unborn in this country."

For decades certain human beings were wrongly treated as property and denied liberty in America because they were not considered persons under the constitution. Today other human beings, the unborn of all races, are also wrongly treated as property and denied the right to life for the same reason; because they are not considered persons under the constitution. I am disappointed that President Obama, who rightfully fights for civil rights, refuses to recognize the civil rights of the unborn in this country.

Santorum had said in an interview with CNS News yesterday that he can't understand how Obama could not answer whether a "human life" is protected by the Constitution from the moment of conception: "I find it almost remarkable for a black man to say, 'we're going to decide who are people and who are not people.'"
